Home » Law Enforcement

Law enforcement is more than just a concept. It’s a crucial part of our society. Police officers and state troopers prevent, detect, and investigate crime, and apprehend criminals in neighborhoods like yours all across the country, so there’s no denying their importance.

Law enforcement is carried out by more than just patrol officers—those men and women who protect and serve in our communities—and all the way up to detectives, criminal investigators, forensic analysts, and FBI agents. But no matter what their job title, they all share one goal: protecting us from harm and pursuing wrongdoers.

This is a great job for people who want to make a difference. And one of the best ways to prepare, especially if you plan on working up the chain of command, is to get a degree in criminal justice or a law enforcement degree online.


Most police officers patrol their cities and towns, and investigate suspicious activity. They warn, cite, or arrest people who break the law. They respond to emergency calls and may give first aid since they’re often the first responders at accidents.

Police officers also conduct traffic stops and give tickets, obtain warrants, arrest suspects, write reports, and testify in court.

Law enforcement officers work for cities, counties, states, and the federal government (the FBI, Drug Enforcement Agency, Secret Service, and more).

The daily activities of police and detectives vary depending on their particular specialty, such as special weapons and tactics (SWAT), arson, homicide, missing persons, vice squad, bomb squad, canine unit (K9), narcotics, and more.

It’s a challenging career; no two days are the same. You’ll get a sense of doing good in your community, it’s well paid, and, if you have the aptitude and desire, you’ll love your work.
